The engine oil pressure warning light is not
designed to indicate a low oil level. Use the
dipstick to check the oil level.See ªEngine
oilº in the ª8. Maintenance and do-it-yourselfº
section.
CAUTION
Running the engine with the engine oil
pressure warning light on could cause
serious damage to the engine almost
immediately. Turn off the engine as
soon as it is safe to do so.
Low tire pressure warning light
(if so equipped)
The light comes on for about 1 second when the
key switch is turned ON, and then it turns off.
If the vehicle is being driven with a flat tire or
extremely low tire pressure, the light will illumi-
nate. Also a chime will sound for about 10
seconds if a tire is flat.
For additional information, see ªLow tire pres-
sure warning systemº in the ª5. Starting and
drivingº section and ªFlat tireº in the ª6. In caseof emergencyº section. Also, you can check the
tire pressure of all 4 tires on the trip computer
display. See ªTrip computerº earlier in this sec-
tion.
WARNING
IIf the light does not come on with the
key switch turned ON, have the ve-
hicle checked by a NISSAN dealer as
soon as possible.
IIf the light comes on while driving,
avoid sudden steering maneuvers or
abrupt braking, reduce vehicle speed,
pull off the road to a safe location
and stop the vehicle as soon as pos-
sible. Serious vehicle damage could
occur and may lead to an accident
and could result in serious personal
injury. Check the pressure for all four
tires and adjust the pressure to the
COLD tire pressure shown on the tire
placard. If the light still comes on
while driving after adjusting the tire
pressure, a tire may be flat. If you
have a flat tire, replace it with a spare
tire as soon as possible.IWhen a spare tire is mounted or a
wheel is replaced, tire pressure will
not be indicated and the low tire
pressure warning system will not
function. Contact your NISSAN
dealer as soon as possible for tire
replacement and/or system reset-
ting.
CAUTION
IThe low tire pressure warning is not a
substitute for the regular tire pres-
sure check. Be sure to check the tire
pressure regularly.
IIf the vehicle is being driven at
speeds of less than 20 MPH (32
km/h), the low tire pressure warning
system may not operate correctly.
IBe sure to install the specified size
for the front and rear tires.

While the actuator is working, you may feel a
pulsation in the brake pedal and hear a noise or
vibration from the actuator under the hood. This
is normal and indicates that the anti-lock system
is working properly. However, the pulsation may
indicate that road conditions are hazardous and
extra care is required while driving.Self-test featureThe anti-lock brake system consists of electronic
sensors, electric pumps, and hydraulic solenoids
controlled by a computer. The computer has a
built-in diagnostic feature that tests the system
each time you start the engine and move the
vehicle at a low speed in forward or reverse.
When the self-test occurs, you may hear a clunk
noise and/or feel a pulsation in the brake pedal.
This is normal and is not an indication of any
malfunction. If the computer senses any mal-
function, it switches the anti-lock brake system
OFF and turns on the ABS warning light in the
dashboard. The brake system will then behave
normally, but without anti-lock assistance.
If the light comes on during the self check, or
while you are driving, you should take your
vehicle to your NISSAN dealer for repair at your
earliest convenience.
WARNING
The anti-lock brake system is a sophis-
ticated device, but it cannot prevent ac-
cidents resulting from careless or dan-
gerous driving techniques. It can help
maintain vehicle control during braking
on slippery surfaces, but remember that
the stopping distance on slippery sur-
faces will be longer than on normal
surfaces, even with the anti-lock sys-
tem. Stopping distances may also be
longer on rough, gravel or snow covered
roads, or if you are using tire chains.
Always maintain a safe distance from
the vehicle in front of you. Ultimately,
the responsibility for safety of yourself
and others rests in the hands of the
driver.
Tire type and condition of tires may also
affect braking effectiveness.
IWhen replacing tires, install the
specified size for the front and rear
tires.IWhen installing a spare tire, make
sure it is the proper size and type as
specified on the tire placard. See
ªVehicle identificationº in the ª9.

FREEING A FROZEN DOOR LOCKTo prevent a door lock from freezing, apply
de-icer or glycerin to it through the key hole. If
the lock becomes frozen, heat the key before
inserting it into the key hole.ANTI-FREEZEIn the winter when it is anticipated that the
temperature will drop below 32ÉF (0ÉC), check
anti-freeze to assure proper winter protection.
For additional information, see ªEngine Cooling
Systemº in the ª8. Maintenance and do-it-
yourselfº section.BATTERYIf the battery is not fully charged during extremely
cold weather conditions, the battery fluid may
freeze and damage the battery. To maintain
maximum efficiency, the battery should be
checked regularly. For additional information,
see ªBatteryº in the ª8. Maintenance and do-it-
yourselfº section.DRAINING OF COOLANT WATERIf the vehicle is to be left outside without anti-
freeze, drain the cooling system by opening the
drain plug located under the radiator. Refill
before operating the vehicle. See ªEngine cool-
ing systemº in the ª8. Maintenance and do-it-
yourselfº section for changing engine coolant.
TIRE EQUIPMENT1. SUMMER tires are of a tread design to
provide superior performance on dry pave-
ment. However, the performance of these
tires will be substantially reduced in snowy
and icy conditions. If you operate your vehicle
on snowy or icy roads, NISSAN recommends
the use of MUD & SNOW or ALL SEASON
tires on all four wheels. Please consult your
NISSAN dealer for the tire type, size, speed
rating and availability information.
2. For additional traction on icy roads, studded
tires may be used. However, some provinces
and states prohibit their use. Check local,
state and provincial laws before installing
studded tires.
Skid and traction capabilities of studded
snow tires, on wet or dry surfaces, may be
poorer than that of non-studded snow
tires.
3. Tire chains may be used if desired. Make sure
they are of proper size for the tires on your
vehicle and are installed according to the
chain manufacturer's suggestions. Use of tire
chains may be prohibited according to loca-
tion. Check the local laws before installing
tire chains. When installing tire chains, make
sure they are of proper size for the tires on
your vehicle and are installed according tothe chain manufacturer's suggestions.Use
only SAE Class S chains.Class ªSº chains
are used on vehicles with restricted tire to
vehicle clearance. Vehicles that can use
Class ªSº chains are designed to meet the
SAE standard minimum clearances between
the tire and the closest vehicle suspension or
body component required to accommodate
the use of a winter traction device (tire chains
or cables). The minimum clearances are de-
termined using the factory equipped tire size.
Other types may damage your vehicle. Use
chain tensioners when recommended by the
tire chain manufacturer to ensure a tight fit.
Loose end links of the tire chain must be
secured or removed to prevent the possibility
of whipping action damage to the fenders or
underbody. If possible, avoid fully loading
your vehicle when using tire chains. In addi-
tion, drive at a reduced speed. Otherwise,
your vehicle may be damaged and/or vehicle
handling and performance may be adversely
affected.
Never install tire chains on a T-type spare tire.
Do not use tire chains on dry roads.
SPECIAL WINTER EQUIPMENTIt is recommended that the following items be
carried in the vehicle during winter:

For models equipped with the low tire
pressure warning system:
After adjusting tire pressure to the COLD tire
pressure, the display of the tire pressure infor-
mation may show higher pressure than the
COLD tire pressure after the vehicle has been
driven more than 1 mile (1.6 km). This is because
the tire pressurizes as the tire temperature rises.
This does not indicate a system malfunction.
WARNING
Retighten the wheel nuts when the ve-
hicle has been driven for 600 miles
(1,000 km) (also in cases of a flat tire,
etc.).Stowing the tire and toolsSecurely store the spare tire and jacking equip-
ment in the vehicle.
WARNING
IAlways make sure that the spare tire
and jacking equipment are properly
secured after use. Such items canbecome dangerous projectiles in an
accident or sudden stop.
IThe T-type spare tire and small size
spare tire are designed for emer-
gency use. See ªWheels and tiresº in
the ª8. Maintenance and do-it-
yourselfº section.To start your engine with a booster battery, the
instructions and precautions below must be
followed.
WARNING
IIf done incorrectly, jump starting can
lead to a battery explosion, resulting
in severe injury or death. It could also
damage your vehicle.
IExplosive hydrogen gas is always
present in the vicinity of the battery.
Keep all sparks and flames away
from the battery.
IDo not allow battery fluid to come
into contact with eyes, skin, cloth or
painted surfaces. Battery fluid is a
corrosive sulphuric acid solution
which can cause severe burns. If the
fluid should come into contact with
anything, immediately flush the con-
tacted area with water.

parked for 3 or more hours, or driven less than 1
mile (1.6 km) at moderate speeds. COLD tire
pressures are shown on the tire placard affixed
to the inside of the console box lid.Low tire pressure warning system (if
so equipped)The low tire pressure warning system displays
the tire pressure of all tires (except the spare tire)
on the trip computer by sending a signal from a
sensor that is installed in each wheel. For more
details, refer to ªTrip computerº and ªLow tire
pressure warning lightº in the ª2. Instruments
and controlsº section, ªLow tire pressure warn-
ing systemº in the ª5. Starting and drivingº
section, and ªFlat tireº in the ª6. In case of
emergencyº section. If the tire pressure dis-
played on the trip computer is lower than the
COLD tire pressure shown on the tire placard,
check the pressure of all four tires and adjust
them to the COLD tire pressure as indicated
above. The low tire pressure warning system will
activate only when the vehicle is driven at
speeds above 20 MPH (32 km/h).
WARNING
IImproperly inflated tires can fail sud-
denly and cause an accident.IThe vehicle capacity weight is indi-
cated on the tire placard. Do not load
your vehicle beyond this capacity.
Overloading your vehicle may result
in reduced tire life, unsafe operating
conditions due to premature tire fail-
ure, or unfavorable handling charac-
teristics and could also lead to a
serious accident. Loading beyond the
specified capacity may also result in
failure of other vehicle components.
IBefore taking a long trip, or when-
ever you have loaded your vehicle
heavily, use a tire pressure gauge to
ensure that the tire pressure is at the
specified level.
IDo not drive your vehicle over 85
MPH (140 km/h) unless it is equipped
with high speed capability tires. Driv-
ing faster than 85 MPH (140 km/h)
may result in tire failure, loss of con-
trol and possible injury.

tires, refer to ªImportant Tire Safety
Informationº (US) or ªTire Safety In-formationº (Canada) in the Warranty
Information booklet.
TYPES OF TIRES
WARNING
IWhen changing or replacing tires, be
sure all four tires are of the same
type (for example, summer, all sea-
son or snow) and construction. Your
NISSAN dealer may be able to help
you with information about tire type,
size, speed rating and availability.
Replacement tires may have a lower
speed rating than the factory
equipped tires, and may not match
the potential maximum vehicle
speed. Never exceed the maximum
speed rating of the tire.

All season tiresNISSAN specifies all season tires on some
models to provide good performance for use all
year around, including snowy and icy road con-
ditions. All season tires are identified by ALL
SEASON and/or M&S on the tire sidewall. Snow
tires have better snow traction than all season
tires and may be more appropriate in some
areas.Summer tiresNISSAN specifies summer tires on some models
to provide superior performance on dry roads.
Summer tire performance in snow and ice will be
substantially reduced. Summer tires do not have
the tire traction rating M&S on the tire sidewall.
If you operate your vehicle in snowy or icy
conditions, NISSAN recommends the use of
snow or all season tires on all four wheels.Snow tiresIf snow tires are needed, it is necessary to select
tires equivalent in size and load rating to the
original equipment tires. If you do not, it can
adversely affect the safety and handling of your
vehicle.
Generally, snow tires will have lower speed
ratings than factory equipped tires and may not
match the potential maximum vehicle speed.Never exceed the maximum speed rating of the
tire.
If you operate your vehicle in snowy or icy
conditions, NISSAN recommends the use of
snow or all season tires on all four wheels.
For additional traction on icy roads, studded tires
may be used. However, some provinces and
states prohibit their use. Check local, state and
provincial laws before installing studded tires.
Skid and traction capabilities of studded snow
tires, on wet or dry surfaces, may be poorer than
that of non-studded snow tires.
TIRE CHAINSUse of tire chains may be prohibited according
to location. Check the local laws before installing
tire chains. When installing tire chains, make
sure they are of proper size for the tires on your
vehicle and are installed according to the chain
manufacturer's suggestions.Use only SAE
class S chains.Class ªSº chains are used on
vehicles with restricted tire to vehicle clearance.
Vehicles that can use Class ªSº chains are
designed to meet the SAE standard minimum
clearances between the tire and the closest
vehicle suspension or body component required
to accommodate the use of a winter traction
device (tire chains or cables). The minimum
clearances are determined using the factory
equipped tire size. Other types may damageyour vehicle. Use chain tensioners when recom-
mended by the tire chain manufacturer to ensure
a tight fit. Loose end links of the tire chain must
be secured or removed to prevent the possibility
of whipping action damage to the fenders or
undercarriage. If possible, avoid fully loading
your vehicle when using tire chains. In addition,
drive at a reduced speed. Otherwise, your ve-
hicle may be damaged and/or vehicle handling
and performance may be adversely affected.
INever install tire chains on a T-type
spare tire.
IDo not use the chains on dry roads.
ITire chains must be installed only on the
rear wheels and not on the front wheels.
CHANGING WHEELS AND TIRES
Tire rotationTires cannot be rotated in this vehicle, as front
tires are different size from rear tires and the
direction of wheel rotation is fixed in each tire.
A pin is on the front brake rotor to prevent the
rear wheels from being installed in place of the
front wheels. The spare tire can be installed in
place of the front and rear wheels. When install-
ing the spare tire in the front wheel, the hole in
the spare tire wheel must be aligned with the pin
on the brake rotor.

Tire wear and damage
WARNING
ITires should be periodically in-
spected for wear, cracking, bulging,
or objects caught in the tread. If ex-
cessive wear, cracks, bulging, or
deep cuts are found, the tire should
be replaced.
IThe original tires have a built-in tread
wear indicator. When the wearindicator is visible, the tire should be
replaced.
IImproper service for a spare tire may
result in serious personal injury. If it
is necessary to repair the spare tire,
contact your NISSAN dealer.
IFor additional information regarding
tires, refer to ªImportant Tire Safety
Informationº (US) or ªTire Safety In-
formationº (Canada) in the Warranty
Information booklet.
Replacing wheels and tiresWhen replacing a tire, use the same size, speed
rating and load carrying capacity as originally
equipped. See ªSpecificationsº in the ª9. Tech-
nical and consumer informationº section for rec-
ommended types and sizes of tires and wheels.
WARNING
IThe use of tires other than those
recommended or the mixed use of
tires of different brands, construction(bias, bias-belted or radial), or tread
patterns can adversely affect the ride,
braking, handling, ground clearance,
body-to-tire clearance, tire chain
clearance, speedometer calibration,
headlight aim and bumper height.
Some of these effects may lead to
accidents and could result in serious
personal injury.
IIf the wheels are changed for any
reason, always replace with wheels
which have the same offset dimen-
sion. Wheels of a different offset
could cause early tire wear, possibly
degraded vehicle handling character-
istics and/or interference with the
brake discs. Such interference can
lead to decreased braking efficiency
and/or early brake pad wear.
IWhen a spare tire is mounted or a
wheel is replaced, tire pressure will
not be indicated and the low tire
pressure warning system will not
function. Contact your NISSAN

IDo not install a deformed wheel or
tire even if it has been repaired. Such
wheels or tires could have structural
damage and could fail without warn-
ing.
IThe use of retread tire is not recom-
mended.
IFor additional information regarding
tires, refer to ªImportant Tire Safety
Informationº (US) or ªTire Safety In-
formationº (Canada) in the Warranty

Wheel balanceUnbalanced wheels may affect vehicle handling
and tire life. Even with regular use, wheels can
get out of balance. Therefore, they should be
balanced as required.
Wheel balance service should be performed
with the wheels off the vehicle. Spin balancing
the front wheels on the vehicle could lead to
transmission damage.For additional information regarding tires, refer to
ªImportant Tire Safety Informationº (US) or ªTire
Safety Informationº (Canada) in the Warranty
Information booklet.
Care of wheelsIWash the wheels when washing the vehicle
to maintain their appearance.
IClean the inner side of the wheels when the
wheel is changed or the underside of the
vehicle is washed.
IDo not use abrasive cleaners when washing
the wheels.
IInspect wheel rims regularly for dents or
corrosion. Such damage may cause loss of
pressure or poor seal at the tire bead.
INISSAN recommends that the road wheels
be waxed to protect against road salt in areas
where it is used during winter.Spare tire (T-type spare tire)Observe the following precautions if the T-type
spare tire must be used, otherwise your vehicle
could be damaged or involved in an accident.
CAUTION
IThe T-type spare tire should be used
only for emergency. It should be re-
placed by the standard tire at the first
opportunity.
IDrive carefully while the T-type spare
tire is installed.
Avoid sharp turns and abrupt braking
while driving.
IPeriodically check the T-type spare
tire inflation pressure, and always
keep it at 60 psi (420 kPa, 4.2 bar).
IAlways keep the pressure of the full
size spare tire (if so equipped) at the
recommended pressure for standard
tires, as indicated on the tire placard.
